A problem many boaters have is the unequal interests of their spouses in their real or imagined cruising adventures and, most specifically in "sailing" cruising adventures. Along came an East Coast customer who wished to spend the second half of his life with his wife continuing as his partner. It's always a ticklish design issue, attempting to make a boat comfortable and unique enough to hold the interest of a less-than-eager spouse, yet capable and challenging enough to hold the interest and enthusiasm of the more experienced partner.
The Oysta 42 was specified to be a "motor sailer." And not just a sailboat with an auxiliary engine. The Oysta 42 is a true 50/50 motor sailer capable of motoring through any sea condition; with the sail-assist it's capable of doubling its useful cruising range from 1500 miles under power alone to better-than-3,000 miles with sail. And keeping an engine running affords a lot of comfort and luxury on board, while sail alone might work against the less willing crew member's enthusiasm. An inboard low aspect ratio ketch rig was chosen to work within the design framework. Both masts are on tabernacles so that the rig can be easily lowered for canal passages. The aft pilot house design was selected allowing a large shaded (with boom canvas) outside deck area for carefree warm weather anchorages.
